CPU running at 90-100% - possibly due to perfmon.exe

Lately my computers CPU has been running at 90-100%, even when I shut things down. It seems to be somewhat triggered by the flash player, even though it doesn't seem to be what's taking up the ridiculous amounts of CPU. What does show up, however, is perfmon.exe. The advice I've seen so far has been to either do a system restore - I tried it once before and the problem went away, but has now come back and my computer says it doesn't have any restore points. The other piece of advice I found was to disable it from starting up when the computer does, but it doesn't show up in msconfig. Advice? I'm very frustrated and tempted to just delete it, because it is driving me mad to not have a working computer. I'm running windows 7.

Hi,

1. Were there any recent changes made to the computer prior to the issue?

 

I would suggest you to follow the steps provided and check if it helps.

 

 

Method 1: Scan your computer from Microsoft Safety Scanner, which would help us to get rid of viruses, spyware, and other malicious software.

The Microsoft Safety Scanner is a free downloadable security tool that provides on-demand scanning and helps remove viruses, spyware, and other malicious software. It works with your existing antivirus software.

Note: The Microsoft Safety Scanner expires 10 days after being downloaded. To rerun a scan with the latest anti-malware definitions, download and run the Microsoft Safety Scanner again.

 

Note: Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss.

 

Method 2:

If the issue persists then try to set your computer in Clean Boot state and then check if the same issue occurs.

By setting your system in clean boot state helps in identifying if any third party applications or startup items are causing the issue.

Hope this information is helpful.

Perfmon is the resource monitor. You opened it when you opened Task Manager. It has nothing to do with the CPU usage apart from showing you that it's being used.

If it's for windows xp or vista, as it says at the MS description, why is it running with Windows 10?
